' 'GAS-KINDLING BURNER;

Application filed May'I, 1922. Serial No. 557,519.

'My .invention relates to a gas burner associated with the fire-box of a cook stove for the'purpose of enabling the fuel or scrap therein to be readily ignited, and the lire thus quickly kindled.

An object of the invention is to provide a kindler of the character described which will permit of feeding the fuel into the fire-box from the front.

Another object of the invention is to provide a gas kindling burner which will throw the flame across the entire length of the tire-box.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth'in the following description ofthe preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that-l do not limit myself to the showing as I may adopt variations of the preferred form within the scope of my invention as set'forth in the claims.

Referring to said drawings: Figure 1 is a perspective view of a stove i -,quipped with the kindler of my invention.

Figure- 2 is a vertical longitudinal section of the upper portion of the firebox;

Figure 3 is a vertical transverse section of said portion of the firebox. i r Y Figure 4 is a horizontal section-of the boxtaken on the line' 44L of Figures.

Gas kindling devices are generally equipped on ranges in which a gas stove 'unitis attached to a stove unit-burning coal, wood, etc.,'the latter unit being genorally known as a kitchen'heater. Thetwo units are in most instances so attached that "the top of the heater or rather the fire-box is coplanar with the usual grating over the top burners of the gas stove unit, and usually agas manifold extends horizontally across the front of both units below the top of the fire-box and grating and serves the kindler and top burners, the kindler pipe generally extending in the fire-box through the front thereof. Extending the manifold across the front of the fire-box and the kindler pipe through the front thereof, prevents in so far as the practicability thereof is concerned, the feeding of the heater from the feed opening at the front of the box, but ordinarily necessitates feeding from the top-a condition both annoying and inconvenient, since frequently it necessitates the removal or replacement of the vessels on the heater top while cooking. In accordance however with my invention the kindler is arranged on the stove in such manner that the fuel may be readily inserted into the fire-box through the said front opening and furthermore enabling the use ofa door of V the downwardly swinging or drop feed type forclosing said opening.

As illustrated in the drawings, the kindler 2 is equipped on a range 3 provided with a Wood and coal unit or kitchen heater 4 which is structurally associated with a set of, top gas'burners 5 and gas ovens 7. Overlying the burners 5 is the usual grating 8 which coplanar with thecooking top '9 of the heater. The top burners 5 and the burners for the ovens are fed from a'manifold 12 which extends horizontallyac'ross made by the said drawings and description,

the front of the stove opposite said top burners, the usual valves 13 being pro' v vided for controlling the flow of gas to the burners. g

The heater as here shown includes a firebox 14, and the top 9 is provided with two holes 16 adapted to be closed'by lids -1.7.

The front of the firebox is provided with a feed opening 18' whichis arranged above. the fire-grate 19 and through whichthe fuel or scraps maybe inserted into the box. The opening 18 is normally closed by a door 21 which is hinged at the bottom so as to swing inn vertical plane.

{Preferably extending lengthwise of the fire-box and lying withoutthe'side wall 22 adjacent theburners 5, is the gas kindler pipe 23. The latter is'provided with' nozzles or jets 24 which project intothefirebox, preferably justabovethe grate 19,

through openings 25 formed in the side.-

wall 22. Arranged over the nozzle 24, and as here shown formed integral with the wall 22, is a hood 27 which keeps" the fuel and ashes in the fire-boxaway from the nozzles. The hood is open at the' bottom and slotted in front of the nozzlesso that while the latter are well protected,"sufficient air for proper combustion of the gas is afforded and the desired projection of the flame is not interfered with.

Connection of the kindler pipe with the manifold 12 is efiected by means of manifold extension 28 which as here shown extends perpendicularly downward at the front of the stove in vertical alignment with the kindler pipe. It will be noted that no portion of the manifold or the kindler is arranged in front of the lire-box particularly at the feed opening and door. In this manner the fuel for the heater may be in serted through the front of the stove, thereby affording the attendant advantages hereinbet'ore alluded to. Control of the flow of gas to the kindl-er is afforded by a valve 31 at the forward end of the kindler pipe.

By referring to Figures 3 and a it will be noted that the kindler pipe extends substantially from the front to the rear end of the fire-box, and that the nozzles are adapted to direct the gas-flame transversely of the box rather than longitudinally thereof as has heretofore been done.

This feature is of considerable importance, as the gas pressure ordinarily available is insuflicient to projectthe gas flame across the fire-box when the nozzles are located at the front and are pointed lengthwise of the fire-box. However with the nozzles positioned at the'side and arranged to direct the flame transversely, the length of the flame will be suflieient to extend completely across the fire-box thereby insuring maximum ignition efliciency as soon as the kindler is lighted.

In the present embodiment of the invention the gas supply pipe 32 extends from the rear of the stove and is connected directly to the manifold extension. It will be further noted that the supply pipe lies parallel to the kindler pipe and that it extends adjacent and along the side of the wall 22, thereby rendering the supply pipe extremely inconspicuous.

I claim:

1. In combination with a stove provided with a set of top gas burners and a fire box having front openings and a grate, a gas kindler pipe fixed outside and adjacent a side wall of said box and extending horizontally th-erealong, jets on said pipe extending into said box through said wall and arranged to discharge into said firebox above the plane of said grate, a hood arranged to cover the portions of the jets which extend through said wall, a gas-feed manifold extending horizontally along the front of the stove, and a pipe connecting the forward end of said hindler pipe to said manifold at a point lying at the same side of said tire box as said kindler pipe.

2.111 a stove provided with a fire-box having a grate, a gas kindler pipe extending horizontally along a wall of said box, nozzles extending from said pipe into said box and arranged to discharge thereinto, and a hood disposed in front of said nozzles and perforated to permit the discharge from the nozzles to be direct-ed through the perforations thereof.

3.111 a stove provided with a lire-box having a grate, a gas kindler pipe fixed out side and adjacent a wall of said box and extending horizontally therealong, jets on said pipe extending into said box through said wall and arranged to discharge into said the box above the plane of said grate, and a hood arranged to cover the jet portions which extend through said wall.

t. In a stove provided with a lire-box, and a top gas burner chamber having a common wall between them, a gas hindler pipe disposed in said chamber to extend horizontally along said wall, and nozzles extending from said pipe through said wall into said box and arranged to discharge thereinto.

5.111 a stove provided with a lire-box and a top-gas burner chamber having a common wall between them, a gas kindler pipe disposed adjacent said wall to extend horizontally therealong, nozzles extending from said pipe into said box and arranged to discharge thereinto, and a common gas manifold for said kindler and the burners of said chamber mounted on said stove and connected to said kindler and gas burners.

6. In a stove provided with a fire-box having a fuel supporting grate and a topgas burner chamber having a wall in common with said fire-box, a kindler burner disposed adajcent said wall substantially at the level of said grate and provided with nozzles arranged to discharge into said firebox, and a common gas manifold for said kindler burner and the burners of said chamber disposed entirely outwardly of said chamber.

7. In a stove provided with a fire-box having a fuel supporting grate and a topgas burner chamber having a wall in common with said firebox, a kindler burner for said fire-box disposed to extend horizontally along said Wall substantially at the level of said grate, and a manifold having an horizontal portion connected to the burners of said chamber and a depending portion connected adjacent its bottom to said kindler burner, said manifold portions being disposed opposite and entirely outwardly of said chamber.

In testimony whereof, I have hereunto set my hand at Oakland, this 7th day of April, 1922.

GEORGE HAMMER.
